SPECIFICATION forming part of Letters Patent N0. 772,831, dated October 18, 1904. Application lecl May l2, 1903. Serial No. 156,809. (No niodel.)l y

To al?, whom it may concern:

Be it known that I, CHARLES ScHoEIELD, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Willows, of which the following is a specification. l

f My invention consists of certain improvements in the willow forming the subject of my Letters Patenty No. 67 5,248, .dated May 28, 1901, the objects of-my present invention connection than before between the deliverygate and the air-relief valve, and to control the delivery of fiber from the machine.

These objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in Which- Figure 1 is a side view of a willow constructed in accordance with my present invention; and Figs. 2, 3, 4:, and 5 are sectional views, on an enlarged scale, illustrating certain details of the machine not shown with sufficient clearness in the general view.

1 represents the casing of the machine, which has suitable bearings for the drum-shaft 2, the latter having at one end a pulley 14, which receives a belt 15, running to a pulley 16 on the shaft of a blast-fan 8 at the top of the casing, these parts being constructed as before, with the exception that the direction of rotation of the fan is reversed, the belt 15 being4 straight instead of crossed. On the opposite end of the shaft 2 is a pulley 17, which by means of a belt 18 drives a pulley 19, (see dotted lines, Fig. 1;) but instead of mounting said pulley 19V upon a shaft extending across the machine, as before, it is free to turn on a short shaft or stud, which can be adjusted in a slotted plate 65, secured to the top of the casing 1, at one side of the same, the slot being concentric with the axis of the drum-shaft 2, so that a spur-pinion 66, which is secured to the pulley, can be adjusted from and toward the transverse shaft 20 of the machine, this shaft carrying the pinion 21 and also a spurwheel 63. Said spur-wheel 68 meshes with the pinion 66, while the pinion 21 meshes with 4the spur-wheel 23, which is mounted so as to turnfreely on a stud or spindle projecting from one side of the casing 1, said spur-wheel 23 being secured to or forming part of a spurpinion 211, which meshes with spur-teeth on theperiphery of the wheel orrdislr 25, whereby the movements of the feed and delivery mechanism of the machine are governed.

The adjustment of the pulley 19 and pinion 66, whichis permitted by the use of the slotted plate 65, enables me to use a pinion 66 or a spur-wheel 63 of any desired size andnumber of teeth, so that the speed of rotation of-l the governing-wheel 25 in respect to the speed of rotation of the drum-shaft 2 can be readily regulated by changing either of these elements 63 or 66 without any change in the drivingpulleys and without slackening or loosening -the driving-belt 18. The present arrangement of spur-gears also permits of a more compact disposal of the same than was adopted in the original machine, access to the feed-apron 11 and feed-rolls 9 and 10 not being interfered with in anyway by the spur-wheel 23, which in the present machine does not project beyond said feed-rolls.

The lower feed-roll 10 is, as in the former machine, directly driven by engagement of an internal segmental rack 27 on the wheel 25- with a spur-pinion 28, secured to the shaft29 of said lower feed-roll, and the inner drum of the feed-belt 11 is likewise driven from the shaft 29 through the medium of a pinion 30 on said shaft, which pinion meshes with a spur-wheel 31, free to turn on a short shaft or spindle carried by a bracket 32 on the side of the machine, said spur-wheel 31 meshing with a pinion 33 on the shaft which carries said inner drum of the feed-belt. In the present instance, however, the shaft 38 of the upper feed-roll 9 is driven directly from the shaft 29 of the lower feed-roll 10 through the medium o f a pair of spur-pinions 37 and 37, as shown in Fig. 5. In the present instance the shaft 29 of the lower feed-roll has in addition to the pinions 28 and 30 a locking-block 100, which when said pinion 28 is not in mesh with the segmental rack 27 engages with a segmental rib 101, formed on the inner face of the wheel 25, so as to effectually prevent any movement of partial rotation of said shaft 29 and of the parts operated therefrom during the intervals between the movements imparted to said shaft by engagement of the segmental rack 27 and pinion 28, the rib 101 being discontinued throughout the extent of said rack 27, as shown in Fig. 2, so as to offer no obstruction to the free rotation of the shaft 29 while the pinion 28 is in mesh with said segmental rack. By reason of this device the feeding mechanism of the' machine is positively locked during the intervals between its movements, and hence none of its parts can be displaced during such intervals. Therefore the pinion 28 always retains the' position in which it was left by the receding segment 27 and is consequently in position to properly engage with the said segment when the latter again advances, injury to the parts such as might be caused by contact of the ends of a pinion-tooth and segment-tooth being thus prevented.

The wheel 25 has on its outer face a projecting pin 26, which acts upon a shoe 40, carried by a sliding bar 41, suitably guided in a loop 45 on the side of the machine, this sliding bar serving to impart movement to the delivery-gate 12 and relief-valve 55 of the machine, as before, the mechanism for effecting this movement, however, beingslightly different and comprising a bell -crank lever 71, mounted upon a suitable stud on the side of the machine and having one arm connected to the sliding' bar 41 and also by a link 73 to the relief-valve 55, the other arm of the lever being connected by a link 49 to the arm 49 on one end of the shaft 50, which carries the delivery-gate 12, the other end of said shaft having an arm 51, with counterbalance-weight 52, as before.

On one end of the casing of the machine, just above the delivery-opening therein, is a fan structure 90, the shaft 91 of the fan being driven from the drum-shaft 2 through the medium of a pulley 94 on said fan-shaft, a pulley 95 on the drum-shaft, and a connectingbelt 96, the purpose of this fan being to remove from the upper edge of the delivery-gate as the latter swings upwardly into closing position any fiber which may have been deposited thereupon, so that there will be no accumulation of fiber upon the upper edge of the delivery-gate to prevent the snug closing of the same.'

The drum-shaft 2 is also provided with another pulley, 102, which through the medium of a belt 103 drives a pulley 104 on a shaft 105, which is mounted in bearings in a swinging frame comprising suitably-connected side bars or arms 106, the latter being' adjustably mounted upon the casing 1 of the machine, so that the frame can be caused to assume different angles of elevation in respect thereto. The shaft 105 carries the lower druin 107 of a delivery-belt 108, whose upper drum 109 is carried by a shaft 110, mounted in brackets 111, adjustable longitudinally on the swinging frame, so as to provide for keeping the belt 108 tight at all times. The liber which is delivered from the machine when the delivery-gate 12 is open is therefore deposited upon this conveyer-belt 108 and is raised thereby to any desired height, so that it can be delivered into a receptacle disposed beneath the upper end of the conveyor, thereby preventing the disposal of the vliber over a large area, which is likely to occur when said liber is delivered directly and forcibly outward from the discharge-opening of the machine. The angular adjustment of the swinging frame is, in the present instance, effected by providing the pivotal end of each frame-bar 100 with segmental slots 112 for the reception of retaining and supporting bolts 118; but other methods of adjustably mounting the frame may be employed without departing from the essential feature of this element of my invention.

Having thus described my invention, 1 claim and desire to secure by Letters Patent-- 1. r1`he combination of the feeding' devices of a willow, the casing having a delivery-opening and a gate for closing the same, means` for alternately operating the feeding devices and opening the delivery-gate, and means for locking the feeding devices when the deliverygate is open, substantially as specified.
